The Cleaning Air Box is used to clean sensors with compressed air. It is suitable
to be used at the measuring location and can be installed outdoors (sun shield
recommended). The integrated compressor (membrane pump) draws in air from
outside through an intake air filter and presses it through the cleaning nozzles
at the sensor. This cleans the sensor element.
The Cleaning Air Box operates at intervals. The pump is switched on and off with
an external switch. A relay contact of the measuring system is used as the
switch. The relay contact is configured and controlled for the cleaning function
via the software of the measuring system.
